TENDER-SCOOP.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed October 11, 1911. Serial No. 654,154.

To all whom it may concern:

Be it known that we, STEPHEN BENNIS and JOHN GILLnN KEPPEL, a subject ofAustriaJ-lungary and a citizen of the United States, respectively,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements inTender-Scoops, of which. the following is a specification.

Our invention relates to tender scoops, which are designed to raisewater from a trough usually placed bet-ween the rails of a railroadtrack, and convey it into a tank usually carried by the tender of thelocomotive. As heretofore constructed, a serious defect in these deviceshas been that, when a scoop on a rapidly moving tender is in operation,part of the water in the trough intended to be conveyed, or raised bythe scoop into the tank on the tender is thrown out or splashed upon theroadway, bridge, or trestle, and is threfore wasted or not util ized forits desired purpose.

The action of a scoop while taking water from a trough is more or lesslike a blunt plow. At speeds of the tender below thirtyfive miles perhour, a wave action is set up in front of the scoop; the water beingpiled up until it falls over the sides of the trough; and at speeds ofthe tender above thirty-five miles per hour, a large part of the wateris splashed or thrown out upon the roadway, bridge, or trestle, due tothe inertia of the waterthe fact that the velocity of the water enteringthe scoop is less than the velocity of the tender.

The main object of our invention is therefore to so design and constructthe scoop that when it is in operation, it will convey the water fromthe trough into the tank on the tender in a manner to greatly reduce thewaste of water that has been heretofore splashed or thrown out of thetrough, upon the roadway, bridge, or trestle.

Our invention further consists in various details of construction of thescoop, which will be more definitely pointed out hereinafter.

In the accompanying drawings :Figure 1 is a side view of our scoop inposition in side elevation; Fig. 2 is an enlarged sectional view of thescoop proper; Fig. 3 is a front view of the scoop looking from theleftof Fig. 2, and Fig. 4 is a detail section through joint R.

A, is the dipper attached to the joint B.

This joint B may be of any design sufiicient to allow the dipper A toswing when the dipper is raised or lowered.

R is a connecting rod which braces and holds the conduit, to which jointR connects the dipper, in position.

A projection A formed on the end of the dipper prevents the splash orspray from leaving the limits of the dipper. The splash or spray willtherefore strike this projection and fall along its sides into the sidechambers E, E, which are situated in the front and on both sides of thedipper (see Fig. 3). The water which is thus collected will be conveyedby these chambers to the rear of the dipper, and then discharged throughthe outlet C. This outlet is situated directly over and near thewater-trough, thus allowing the accumulated or excess water to return tothe trough. The side chambers are given a slight incline toward the rearend of the dipper, as shown in Fig. 2, to facilitate this action.Likewise that part of the water which is piled up in front of the dipperwill fall over the side flanges F, F, and into the side chambers E, E,and thence out at the discharge opening G into the trough. The sides ofthe dipper below the side chambers at G, G, form the mouth or inlet, andthe inward projection of the bottom part G, G, are for the purpose ofpreventing water which is piled up in front of the dipper from passingalong the sides of the dipper, and thence over the sides of the trough,but on the contrary permit the water to pile up in front and fall overthe flange walls F, into the side chambers E, E.

M, is a suitable conduit or tube projecting upward from the dipper, itbeing rigidly secured in place by the bracket 5 and brace rods R, andserves to convey the water raised by the dipper and discharge it intothe tank N of the tender P.

Any suitable means may be employed for the purpose of raising andlowering the dipper into the trough, and it is optional with thosewishing to use this form of dipper which method they may prefer toemploy. As a feasible means for accomplishing this, however, we havedevised the following. A bell crank lever 1 is fulcrumed at 2 on thebracket 3 secured to the tender, and links 4 depend from the forward endof the bellcrank lever to the dipper to which they are connected as at6. A rod 7 is slidably connected with the truck or other part of thetender, and is employed by the engineer to raise and lower the dipper,it being pivotally connected at 8 to the upper end of the bellcranklever. A spring S on this rod is employed to counterbalance the weightof the dipper, it tending. to normally hold the dipper in an elevatedposition, so that to lower the latter this rod is pulled in the oppositedirection by the engineer. When the dipper is lowered into the troughwhen the tender is in operation, water will immediately rush into it,and part will be con veyed through the dipper into the tube or conduitM, and thence into the tank N. Part of the water will also splash orspray into a forward or sidewise direction, while some will pile up infront of the dipper. This is taken care of by the special constructionof dipper as hereinbefore described.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described withoutdeparture from the spirit and scope of the invention, and hence we donot wish to be limited to the exact construction herein set forth, but

Having fully described our invention, what we claim as new and desire tosecure by Letters Patent, is

1. In a tender scoop, the combination with a suitable supporting frame,of a dip per having a forwardly-projecting chamber above the inlet whichwill prevent the splash or spray from discharging upon the roadway,bridge, or trestle, while the scoop is in operation.

2. In a tender scoop, the combination with a suitable supporting frame,of a dipper formed with forwardly and laterally projecting communicatingchambers located above the inlet of the dipper which will prevent'thesplash or spray from discharging upon the roadway, bridge, or trestlewhile the scoop is in operation.

3. In a tender scoop, the combination with a suitable supporting frame,of a dipper formed with forwardly and laterally projecting communicatingchambers located above the inlet of the dipper, said chambers decreasingin height toward the rear, and having a discharge outlet at the rear ofthe dipper located over the trough.

4:. In a tender scoop, the combination with a suitable support, of adipper formed with a projecting chamber, side chambers and side flangesall located above the inlet of the dipper, said chambers communicatingand having a common outlet at the rear of the dipper.

5. In a tender scoop, a dipper having an inlet which leads to adischarge conduit or tube, and provided with a chamber which projectsforward of the inlet and side chambers on either side thereof, saidchambers located above the inlet with a flange wall partially separatingsaid chambers from the inlet, and a centrally located rear outlet fromsaid chambers.

6. In a tender scoop, a dipper having an inlet which leads to adischarge conduit or tube, and provided with a chamber which projectsforward of the inlet, side chambers on either side thereof, saidchambers located above the inlet with a flange wall partially separatingsaid chambers from the inlet, and a centrally located rear outlet fromsaid chambers, said chambers decreasing in size and capacity from theirforward to their rear ends.

7. In a tender scoop, the combination with a suitable supporting frame,of a dipper having a forwardly opening inlet and rearwardly dischargingoutlet, and provided at the sides of the inlet with inwardly projectingflanges and chambers to take the splash and spray located above theinlet and extending forwardly and laterally upon either side thereof,said chambers reducing in size toward the rear and provided with anoutlet at or near their rear ends.

In testimony whereof we affix our signatures, in the presence of twowitnesses.
